Polkadot Parachains: A Complete Guide

Polkadot parachains have been the buzz of the crypto town lately, with up to 100 parachains in the ecosystem, boosting the circulating supply of DOT to nearly 1.48 billion. This rapid increase, complemented by a staking rate of 58.82%, demonstrates the huge potential of these blockchain structures.

What are Polkadot Parachains?

Polkadot Parachains are specialized, independent blockchains that serve as an important scaling option inside the Polkadot ecosystem. They run in parallel to the main Polkadot Relay Chain, using its security and consensus methods, hence the name “parachains”.

Essentially, each parachain functions as a custom-built Layer 1 blockchain, complete with its own governance structure, tokenomics, and rules. Unlike standalone blockchains, parachains capitalize on Polkadot's shared security and interoperability capabilities.

The Importance of Polkadot Parachains

Parachains were developed to overcome the constraints of early blockchains, which, despite their proliferation, were isolated and lacked interoperability. This hindered scalability and widespread adoption, much like a world of disconnected islands.

The vision was to establish an "internet of blockchains"—a network that would enable diverse blockchains to interact in a seamless manner while maintaining their sovereignty.

Parachains emerged as the solution, providing the ability for decentralized applications (dApps) to operate autonomously while enabling cross-chain communication and shared security.

Features and Benefits of Polkadot Parachains

Polkadot parachains are sovereign Layer-1 blockchains, meaning they can host numerous decentralized apps (dApps) and even smart contracts, something the Polkadot Relay Chain lacks. From decentralized exchanges (DEXs) and DeFi platforms to NFT marketplaces and gaming ecosystems, parachains are diverse tools for shaping the future of Web3.

Additionally, they offer a variety of important characteristics and benefits, including:

• Customization: Parachains are highly adaptable, enabling developers to tailor their chain's parameters, such as consensus mechanisms and tokenomics, to suit specific use cases.
• Interoperability: Thanks to Polkadot's cross-consensus messaging (XCM), parachains can seamlessly interact and exchange data with other parachains and external networks, unlocking a new era of cross-chain collaboration.
• Scalability: By processing transactions in parallel, parachains significantly enhance the scalability of the Polkadot network, allowing it to handle a high volume of transactions efficiently.
• Shared Security: Parachains inherit the robust security of the Polkadot Relay Chain, ensuring a safe and trustless environment for users and developers.
• Governance: Parachains can implement their own on-chain governance systems, empowering communities to actively participate in decision-making and shape the future of their chain.

Polkadot Parachains vs Polkadot Parathreads

Now that you know about Polkadot parachains, there's another term floating around the Polkadot ecosystem that sounds awfully similar: parathreads. To be honest, it’s easy to get them mixed up. Let’s break down these two concepts and shed some light on how they fit into the grand scheme of Polkadot.

• Parachains: These are permanent, dedicated blockchains that have secured a slot on the Polkadot Relay Chain through an auction process. They offer the highest level of security and interoperability.
• Parathreads: These are temporary, pay-as-you-go blockchains that share a pool of validators with other parathreads. They are a more cost-effective alternative for projects with lower transaction volumes or intermittent activity.

Notable Projects Based on the Polkadot Parachain Network

The Polkadot ecosystem is home to an increasing number of creative and ambitious initiatives, each of which uses the power of parachains to solve unique issues and generate new possibilities. Let's look at four examples that highlight the Polkadot parachain network's adaptability and potential.

#1: Origin Trail

Origin Trail is a decentralized knowledge graph that combines blockchain technology with knowledge graphs to generate AI-ready knowledge assets. Origin Trail combines these cutting-edge technologies to allow the analysis and refining of different data, ranging from the metaverse to supply chains.

#3: Astar

Astar is developing itself as a smart contract hub on the Polkadot network, providing developers with a flexible platform for creating dApps that function with both the Ethereum Virtual Machine (EVM) and WebAssembly. This flexibility broadens the variety of options for developers, allowing them to construct new apps that take advantage of the strengths of both platforms.

Astar's DApp staking system is a novel feature that compensates developers for their efforts. Staking tokens on their dApps allows developers to earn extra incentives depending on the use and popularity of their apps. This offers a long-term incentive mechanism that promotes innovation and high-quality development on the Astar network.

How to Start a Parachain on Polkadot?

Launching a parachain on Polkadot entails acquiring a desirable spot on the Relay Chain via a competitive auction. Here's a simple guide:

1. Participating in parachain slot auctions: Polkadot employs a competitive auction system to allocate parachain slots. Interested parties bid using DOT tokens, and the highest bidder wins the lease.
2. Locking up DOT for the lease period: The winning bidder must lock up their DOT tokens for the duration of the lease, which can range from six months to two years. These tokens are held in reserve and cannot be used for other purposes (such transferring or staking) during this time.
3. Funding your bid: You can self-fund your bid or utilize crowd loans, where DOT holders contribute their tokens in exchange for potential rewards if your bid is successful.
4. Launching and maintaining: After development, launch your parachain and actively maintain its operation. Remember, parachain slots are leased, so you'll need to renew your lease through future auctions to continue operating on Polkadot.

While securing a parachain slot via an auction is the preferred approach, there are other options to explore, such as:

• Utilizing Polkadot parathreads: If your project does not need a full-time parachain slot, Polkadot parathreads provide a flexible, pay-as-you-go solution.
• Securing from secondary markets: Another option is to acquire a parachain slot via a secondary market, where someone who has already secured a slot resells it, and the associated deposit of locked tokens goes to a buyer.
• Receiving granted slots: In rare situations, initiatives considered critical to the Polkadot ecosystem may get slots directly via the governance process.
